forgive me if this is a silly question, i'm new. I am trying to get hair physics working on the base character when i export to unreal. The tutorial video i have been watching ( https://www.youtube.com/watch?v=dbEqWp-Z-bo ) adjusts the characters physics to stop it messing up the hair simulation, however, when i go to look at this the physics details panel is completely empty, am i missing a setting when i export?, why can't i see the physics elements like in the video at 4:28?
